Frequently Asked Questions
Do these ratios work for all recipes?
These are standard baking substitution ratios that work well in most recipes, but results can vary slightly with cakes, cookies, or bread due to differences in moisture and fat content.
Why does butter-to-oil use a 0.75 ratio?
Butter contains water and milk solids, so when substituting with pure oil, you typically need about 25% less volume to match the fat content.
How do I use the flax egg substitute?
Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water per egg, then let it sit for about 5 minutes to gel before adding to your batter.
